Array.prototype.toSource() - JavaScript 编辑

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The toSource() method returns a string representing the source code of the array.

Syntax

arr.toSource()

Return value

A string representing the source code of the array.

Description

The toSource method returns the following values:

• For the built-in Array object, toSource returns the following string indicating that the source code is not available:

  function Array() {
      [native code]
  }
  

• For instances of Array, toSource returns a string representing the source code.

This method is usually called internally by JavaScript and not explicitly in code. You can call toSource while debugging to examine the contents of an array.

Examples
